Emily: Can't believe Rafael Nadal - absolutely brilliant. Just destroyed a really impressive young player as if he were an amateur - brutal. My fave since emerging all those years ago in his teens, & continues to amaze in his 30s. So lovely & humble too.

More from Rafael Nadal, on beating up and coming players: "The youngsters are good and are improving every month. It's always a big challenge to play against them. It's the beautiful thing about this sport there is a young and new generation forming. They are here already and fighting for the most important things."
Can Tsitsipas win majors?
"He has everything to be a multi Grand Slam champion. I hope to face him in important rounds in the next couple of years."
On the other semi-final between Novak Djokovic and Lucas Pouille:
"Novak is the favourite and for Lucas it's the first one. Lucas had one amazing match in the quarters. I always thought Lucas has amazing potential - he can beat anyone at his best."

Rafael Nadal has just been speaking to John McEnroe and says: "Hopefully I can [play better than that]. It's been a great match and a great tournament. This court and this crowd gave me that unbelievable energy.
"To be in the final for the fifth time feels really good. A few weeks ago when I was in Brisbane having to say I couldn't play there it was difficult to imagine that I would be here. Since the tournament started I have felt really, really well.
"Thanks to everybody who sends messages when I'm in a low moment."

Finlay Donaldson: So much for the changing of the guard, as proclaimed by John Mcenroe. One scalp doesn't mean you've made it. Still an excellent tournament for @StefTsitsipas, external, excited to see him at the French.
Sam: You can see in Nadal's play, he is hungry for this title. So many troubles here in the past. - 2014 injury in the finals - last year's in the quarters to name a few. He looks so hungry now. Can't wait for the finals.

Stefanos Tsitsipas looks dejected as Nadal now holds a triple break. Magnificent and relentless from the Spaniard. One of the best performances you could ever see in a Grand Slam semi-final.
Tsitsipas has not played badly, but is on the verge of a crushing three-set defeat, but his time will definitely come again. Nadal to serve for the match.
